OIL-BURNER.

Specification of Letters Patent.

Patented Oct. 27, 1914.

Application filed May 28, 1913. Serial N 0. 770,496.

To all whom it may concern:

Be it known that I, CHRISTIAN M. HEIN- SEN, a citizen of the United States, residing at Fresno, in the county of Fresno, State of California, have invented certain new and useful Improvements in Oil-Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. p

This invention relates to oil burners.

The object of the invention resides in the provision of an oil burner which embodies an improved construction for finely dividing the oil and mixing same thoroughly with a suitable quantit of steam previous .to the passage of the 011 to the burner tip.

With the above and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out in the appended claim. 4

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters of reference denote corresponding parts in the several'vie'ws, and in which- Figure 1 is a plan view of an oil burner constructed in accordance with the invention with the burner tip omitted; Fig. 2, is

a horizontal section of what is shown in Fig. 1, and Fig. 3, a sectionon the line 3-3 of Fig. 1.

Referring to the drawings the burner is shown as comprising a tubular body portion 10 which is threaded at one end for the reception of a burner tip as at 11. The bore .of the tubular body portion 10 is contracted centrally as at 12 and said body portion is enlarged intermediate its ends to form a fan wheel casing 13 the interior of which communicates with the contracted ortion of the bore of the body 10 and also interrupts said bore so that material passing through the bore must of necessity pass through a portion of the interior of the fan wheel casing. Rotatably mounted in the casing 13 is a fan wheel 14 which operates as a mixing device as will hereinafter appear. The end of the bore of the body 10 remote from the threads 11 is threaded as at 15 and engaged with these threads is a steam supply pipe 16. This supply pipe 16 terminates in a nozzle 17 having a less diameter than the bore of the body 10 so that a space is formed between said nozzle and the wall of the bore. The outer end of the nozzle 17 is tapered as at 18 to conform to thecontracted portion of the bore of the body 10 and is positioned to direct steam against the blade of the fan wheel 14 and effect the rotation of the latter. The body 10 is provided between the threads 15 and the outer end of the nozzle 17 with a threaded transverse opening '19 communicating with the bore of said body and engaged in this threaded opening 19 is one end of an oil supply pipe 20.

In the operation of the burner steam is turned into the pipe 16 from whence it passes through the nozzle 17 and against the fan wheel 14. At the same time oil is delivered in the space between the nozzle 17 and the wall of the bore of the body 10. This oil is heated and rendered more fluid by the steam passing through the nozzle 17 and is then drawn against the fan wheel 14: by the vacuum which is created by the jet of steam issuing from the nozzle 17.

What I claim is An oil burner comprising a tubular body having its bore contracted intermediately and said body having an enlarged portion forming a fan wheel casing, the interior of which interrupts the bore of the body at the contracted portion thereof, a fan wheel rotatably mounted in said casing with its axis of rotation at right angles to the axis of the body and its blades completely obstructing the bore of the body, a steam supply pipe engaged in one end of the bore of said body and terminating in a nozzle disposed within the bore of the body and of less diameter than said bore, means for delivering oil into the bore of the body between the ends of said nozzle, and means at the other end of said body for the attachment of a burner tip.

In testimony whereof, I affix my signature, in the presence of two witnesses.

CHRISTIAN M. HEIN SEN.
